Application filed'il'anuary 18, 1900. Serial No. 1,950. (No model.)

To ctZZ 1071 0112, it 72mg concern.-

Be it known that I, OLIVER H. P. SHROYER, a citizen of the UnitedStates, residing at St. Louis, in the State of Missouri, have inventedcertain new and useful Improvements in M0- tor-Plows; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in motor-plows and it consists inthe novel com: bination and arrangements of parts, as will behereinafter more particularly described and claimed.

In the drawings, Figure 1 is a combined top plan and sectional view ofmy complete invention with the steering apparatus removed therefrom.Fig. 2 is a side elevation of the same with parts broken away. Fig. 3

is a section taken on the line a: x of Fig. 1,

showing the mechanism for elevating one side of the frame of themachine. Fig. 4 is adetail section of the reversing-gearing. Fig. 5 is aside elevation in detail, showing the mechanism for raising the plows.Fig. 6 is a vertical section of the front portion of the machine,showing the arrangement ofthe steering apparatus; and Fig. 7 is a frontelevation, with parts broken away, of said steering apparatus.

The object of my invention is to construct a practical, durable, andeffective motor-plow whereby horses are entirely dispensed with, themotor-power employed being of any suitable nature, such as agasolene-engine, steamengine, compressed air, or electric motor, any ofwhich may be practically connected to the propelling-shaft of themotor-plow, and the latter is of such a construction that by theemployment of suitable hand-levers the plows are practically raised andlowered, the gearing for propelling the machine being properlycontrolled, whereby said machine may be stopped or propelled forward orbackward, as may be desired, without disconnecting the gearing or wheelsforminga part of the same, suitable mechanism for raising or elevatingone side of the frame of the machine, whereby the plows may be thrown atan angle to the ground to be operated upon, and in other details in theconstruction, as will be hereinafter more specifically described.

Referring to the drawings, 1 represents a frame of suitable design, and2 an engine or motor mounted upon said frame and provided with areciprocating pitman 3, the forward end of which is attached in theusual manner to the power-shaft 4, and 5 a balance or fly wheel fixed tosaid shaft and having the usual function, the said shaft being journaledin bearings 6, forminga part of the engine-frame. Fixed to the freeprojecting end of the power-shaft 4 is a pinion 7, which meshes with andis interposed between the internal gear 8 and the external gear 9,10

cated within the latter, whereby motion is imparted in either directionto the machine in a manner hereinafter to be described, the lattergearing being more clearly shown in Figs. 1 and 4 of the drawings.Mounted upon the frame 1 of the machine in a transverse direction andimmediately below the powershaft 4 is a shaft 10, upon which is movablymounted the internal gear 8 and the external gear 9, the same beingseparated by a collar 11, fixed to said shaft, the said gearwheels beingmovably coupled together by a collar 12, secured to the internal gear 8and having a depending annular flange 13, which cooperates with acontinuous groove formed on the external gear 9, whereby the two gearsare properly coupled, but movable independently of one another. Theouter portions of the hubs which form a part of the internal andexternal gears 8 and 9, respectively, are provided withcircumferentially arranged depressions 14, which are adapted to receivethe correspondingly shaped projections 15 of the sliding thimbles 16,the latter being movable only in a longitudinal direction upon the shaft10, pins 17 being fixed to said shaft and passing through slots 18,formed in said thimbles, a fork-lever 19, pivoted to a suitable bracket20 and having an operating-handle 21, cooperating with said thimbles inthe usual manner for operating the latter in a longitudinal directionupon the shaft 10, whereby either of the gears 8 and 9 may be fixed tothe shaft 10 or prevented from rotation independently of the same.

From the foregoing description it will be seen by referring particularlyto Fig. 4 of the drawings that when the thimbles are located in theposition as shown both of the gear wheels 8 and i) may be turned uponthe shaft 10, whereby the latter will not be operated or turned; butshould one of the thimbles be brought in contact with eitherone of thesaid gears the same will be locked against rotation independently of theshaft, whereby the lat ter will be operated in the proper direction.

Fixed to the shaft 10 is a pinion 22, which meshes with a gear-wheel 23,also fixed to a transverse shaft 24, the said gear 23 being movable uponthe shaft 2 in a longitudinal direction, whereby the same may bedisengaged from the pinion 22 when it is desired to use the machine as amotor for propelling any suitable farm machinery, a belt-pulley 25 beingfixed to the outer projecting end of the shaft 10, over which a belt isadapted to be passed for this purpose.

Secured to the projecting end of the shaft 2t is a pinion 26, whichmeshes with a gearwheel 27, loosely mounted upon the axle or shaft 28,which also loosely carries one of the d rivewheels 29, and looselyjournaled to the inner periphery of the gear-wheel 27 are a suitablenumber of bevel-pinions 30, which mesh with a bevel gear-wheel 31, fixedto the drive-wheel 29, and also a bevel gear-wheel 32, keyed orotherwise fixed to the shaft 28, whereby when the machine is steered indifferent directions the gearing thus described will adjust itself tothe same, and consequently a direct power is established at all times.

The shaft 28 is properly journaled in the frame 1, and secured to theopposite project.- ing ends of the same is a sprocket-wheel 33, overwhich a sprocket-chain 3t is passed, the latter also passing over asimilar sprocketwheel 35, secured to the opposite wheel 36 of themachine, the last-named sprocket-wheel, together with the wheel 36,being loosely mounted upon a spindle or short shaft 37, fixed to andprojecting from a quadrant 38, the latter being movably mounted upon theshaft 28, whereby when motion is imparted to the said shaft thedrive-wheel 36 will be simultaneously turned with the drive-wheel 29 onthe opposite side of the machine.

In operating the machine it sometimes becomes necessary to throw theframe of the same at an incline to the ground upon which the saidmachine travels in order to give the plows the proper position inrespect to the ground to be operated upon, and in order to accomplishthis feature a bracket 39 is secured to the frame of the machine, thelower portion of which is provided with a segmental guide-slot 4:0,and journaled to the said bracket is one end of an arm 41, the lower free endof which is provided with a pin 42, which cooperates with said slot andprovides means for attaching one end of the rod 43 to the said arm, theopposite end of said rod being movably attached to a handoperating-lever at,

the, lower end of which is pivoted to a segmental guide 45, fixed to theframe of the machine, with which segmental guide the said quadrant 38 isadapted to cooperate, a

stop 46 being secured to the said guide to limit the movement of saidquadrant in one direction, the said hand-lever 44 carrying the usualpawl, which is adapted to cooperate with the segmental rack-bar .7, alsosecured to the frame 1. The quadrant 38 is connected to the pin 42 bymeans of a connecting-rod 48, whereby when the lever 44 is thrown in thedirection as shown by the arrow in Fig. 3 the quadrant 38 is moved inthe direction shown by the arrow, thus elevating that side of the frameof the machine to which this mechanism is attached.

lhe plows which I employ are of any wellknown construction, and in thepresent instance I employ two, the same being designated by the numeral49, which are rigidly coupled together by a cross-bar 50, having anupwardly-projecting arm 51, to the end of which is movably attached oneend of an arm 52, the opposite end of said arm being movably attached toa pin 53, adj ustably secured to a depending bracket 51, secured to theframe 1, and also movable upon the pin 53 is a hand-lever 55, of thewell-known construction, carrying the usualpawl, which is adapted tocooperate with the segmental rack-bar 56, fixed to the machine, wherebysaid lever may be held in any desired position, and projecting from thelower end of said lever is a pin 57, which is adapted to cooperate orcome in contact with the lower edge of the connectingrod 52 forelevating the rear ends of the plows after the forward ends thereof havepreviously been elevated in a manner now to be described.

Rigidly secured to the hand-lever 55 is a short arm 58, to the free endof which is at tached one end of a connecting-rod 59, the opposite endbeing attached to a segmental rocking lever 60, having a projecting arm61, to which is attached one end of a link 62, the opposite end beingattached to a slide 63, the latter being movably attached to the forwardend of the plow, the said slide being movable upon a rod 64:, carried bya bracket 65, secured to the frame of the machine, which bracket or acontinuation thereof forms a bearing for the segmental rocking lever 60.

From the foregoing description it will be seen that when the lever 55 isturned in the direction as shown in the drawings in Fig. 5 the forwardends of the plows will first be elevated out of the ground, after which,or by a further movement of the lever in the same direction, the pin 57will come in contact with the connecting-rod 52 and operate to elevatethe rear ends of the plows, thereby elevating the plows in a practicalmanner out of the ground.

In order to steer the machine or pilot the same, I cm ploy a singleguide-wheel 66, which is journaled in the fork G7 and having forkedextensions (38 leading from-its lower ends, the said forks, togetherwith the wheel 66, being attached to the frame 1 of the machine in amanner now to be described.

The upper portion of the fork 67 is provided with an annular groove forreceiving a series of balls 69, the latter cooperating with a similargroove formed on the lower surface of the frame 1, surrounding thepivotal connection or stem 70, passing through said frame, upon theupper end of which is screwed a nut 71, whereby the said fork is held inits proper position in respect to said frame, and fixed to the said stembetween the upper portion of the fork 67 and that portion of the frameto which the said fork is pivotally connected is a bevel-pinion 72, withwhich cooperates a similar pinion 73, fixed to a short shaft 74, thelatter being journaled in an extension 75 or hearing forming a part ofthe frame, and

fixed to the said short shaft is a gear-wheel 76, with which cooperatesa pinion 77, secured to an operating-shaft 78, properlyjournaled to theframe of the machine, the outer end of which is provided with a handwheel 7 9, whereby the guide-wheel 66 may be turned and held in anyproper position in respect to the machine.

In order to hold the fork 67 in a rigid position in respect to the frameof the machine, the fork 68, forming a part of the same, is providedwith a stem 80, which passes through a slot 81, formed in the forwardend of the frame of the machine, to which stem is movably'attachedrollers 82, which cooperate with the upper and lower fiat surfaces ofsaid portion of the frame, thereby reducing the friction in turning theguide-wheel 66 to a minillllllll.
